✦ Synopsis

To know the influence of initial microstructures before training on the effectiveness of training, the effect of training on the shape memory effect was investigated in a FeMnSiCrNi alloy with different initial microstructures. The results showed that the initial microstructures dramatically influenced the effectiveness of training in FeMnSi shape memory alloys. The effectiveness of training was much better only for the specimens with the initial microstructures not favoring a good shape memory effect. The reason is that in specimens with a good initial SME the decompositions of martensite plates are less since the most of stress-induced martensite reverse to austenite after annealing, not decompose into stacking faults.
